Influence of inf Class GUID in HCT test

Dear all,
I faced a strange situation when I am doing HCT test againest my USB device.

In INF file I gave Class=Security. and I used the calss GUID
{6A923685-D5BD- 11d5-9CE4-005056920001} (I think this is security
calss GUID).

Then in HCT test my driver is coming in USB and Antivirus class.

In INF file I gave class= Security and I used class GUID as given in
BulkUSB sample GUID.

Still in HCT it is coming under Both USB and anti virus class.

What may be the resion?.
Here I am attaching the INF file code snippet with this mail.’

Regards,
Ramya
